monoblue: also highlight target line on annotate and comparison pages Clicking on a line link on pages that show any kind of file contents (including diffs) should highlight that line, and in monoblue it works when there's a <pre> element (e.g. diff), but pages that use <table> element (annotate and compare) need this css class. It matches and highlights linked (":target") table rows. This line is pretty much copied from gitweb theme.
